SPECIFICATION forming part of Letters Patent No. 672,688, dated April23, 1901.

Application filed June 11,1900. Serial No. 19,819. (No model.)

To all whom. it may concern:

Be it known that 1, JAMES Ross VANCE, of Geneva, in the county ofOntario and State of New York, have invented new and useful Improvementsin Steam and Hot -Water Heaters,

of which the following, taken in connection with the accompanyingdrawings, is a full, clear, and exact description.

My invention consists in a new constructioning channels in their rearfaces, by which the water-leg is protected from direct contact with theincandescent coals and the products of combustion are brought quicklyinto uniform contact with the entire outer as well as with the innersurface of the boiler, thus obtaining the maximum of fire-surfaceWithout complicated flues, baffle-plates, 850.

My invention is clearly illustrated in the accompanying drawings, inwhich the same reference-numerals indicate the same parts in all thefigures.

Figure I is a side elevation of a furnace constructed according to myinvention, portions being broken away and portions being shown insection; Fig. II is a corresponding vertical Fig. III is a cross-sectionon line III III of Fig. I. Fig. IV is an isometric view of a singletile. Fig. V is an isometric view of one of the podestals detached.

In the figures, 1 indicates the base, forming an ash-pit provided withthe usual door 2 and having the flat upper plate 4, provided withflanges 5 and 6 for receiving and sustaining the outer shell or jacket11 and the tiles 8 8. To this plate are secured the blocks or pedestals10 10, of suitable form and number to support the boiler 7 above theplate, leaving a space under the lower edge of the water-leg 12 for thepassage of the products of combustion. Such support may be afforded by aperforated ring or other suitable device; but I prefer separatepedestals bolted to the plate, of which a suitable form is shown in Fig.V, having flanges 13 for the securingbolts 14, a bed 15 to support theboiler, and an outer flange 16 for retaining it in position.

18 indicates the inner shell of the boiler, and 19 its outer shell.

The lower part of the fire-box is lined with tiles 8 8, of fire-brick orsimilar fire-resisting material, fitted to the flange on the base-plateand having channels 21 21 on their outer surfaces next the water-leg.These tiles may be variously constructed and of such length, width, andthickness as may be desirable, their essential features being that theyline the lower portion of the water-leg, protecting it from directcontact with the fire, and are provided with channels on their outersurfaces, through which the products of combustion, having impinged onthe inner arch 22 of the com bustion-chamber, pass down in contact withthe inner surface of the water-leg, under the lower edge of the boiler,between the pedestals, thence up and around the outer surface of theboiler through the annular flue 23 within the shell 11 and out of thepipe 25.

If more water-space is desired, one or more water-tubes 26 26 may bearranged connecting the water-legs at such distance above the fire asmay be desirable, as shown in Fig. I, or arranged extending above thefire with a dead end, as in Fig. II.

The other parts of my furnace are of usual construction. 30 indicatesthe water-gage; 31, the steam-gage; 32, the automatic regulator to thedamper 33; 34, the steam-pipe; 35, the clean-out door; 36, the grate, ofany suitable construction, and 37 and 38 doors to the combustion-chamberand fire-box.

My boiler is simple and economical to construct. Expensive andcomplicated fines and baffie-plates are avoided. The water-leg isprotected from direct contact with the fire and the outer edge of thefire itself not cooled by con tact therewith, so that combustion andincandescence throughout the whole fire is uniform and regular. Themaximum of incandescence is not confined to the center of the fire, asin most boilers, and thus the maximum of uniform heat is obtained fromthe fuel, heating the entire inner surface of the boiler uniformly. Theproducts, still at a high temperature, pass down the channels in contactwith the water-leg and are imme- 4o the water-leg from the fire, saidtiles being diately brought in contact with'the entire exterior of theboiler. Thus both surfaces are practically fire-surfaces and the lesseffective flue-surfaces are entirely avoided. The tiles are uniformlyheated on both surfaces, avoiding the danger of warping and breaking.

f My boiler is easy to construct, to ship, and to set up on its separatebase, needs few repairs, is easy to repair when necessary, is easilycleaned, and is very durable. It is eflective in operation, and from itssimplicity of form is comparatively light, unnecessary metallic partsbeing avoided.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, 1's- 1. In combination in a heater, a suitablebase, a boiler supported thereon having a lower annular water-leg andopenings near the lower edge of the water-leg, an external jacketforming a continuous flue around the boiler, and a series of tiles ofrefractory material arranged around the fire-box, in contact with theinner surface of the water-leg, having vertical grooves on their outersurface to conduct the products of combustion down in contact with theinner surface of the water-leg to the openings and the outer flue.

2. In combination in a steam or hot-Water heater, a separate base havinga Hat top formed with flanges for maintaining the position of the upperportionsof the heater set thereon, a boiler also supported on the basehaving the lower annular water-leg inclosing the fire-box formed withopenings at or near its lower edge, an external jacket also supported onthe base inclosing said boiler and forming a continuous flue around itsouter surface, a series of fire-brick tiles lining the fire-box andprotecting the lower portion of formed with grooves on their outer facesto permit the passage of the products of combustion from thecombustion-chamber down to said openings and the outer flue.

3. In combination in a steam or hot-water heater, a separate base havinga fiat top formed with flanges for maintaining in position the upperportions of the heater set thereon, separate pedestals secured on saidflat top to support the boiler and elevate it above said base, thecylindrical boiler having an annular water-leg fitted to said pedestals,a sheet-metal jacket supported on the base to inclose the boiler andform a continuous flue around its outer surface, a series of fire-bricktiles forming a lining around the fire-box to protect the lower portionof the Water-leg from contact with the fire, said tiles being formedwith grooves on their outer surfaces, in contact with the water-leg, topermit the downward passage of the products of combustion from thecombustion-chamber stapes down and under the water-leg to the exterior4. In combination in a steam or hot-water heater, a base of cast metalhaving an annular flat top, concentric flanges formed on said top tomaintain the position of the upper portion of the heater set thereon,separate pedestals secured on said top plate to support the boiler, acylindrical boiler having an annular water-leg fitted to said pedestalsso as to leave openings between the water-leg and the flat plate for thepassage of the products of combustion, a suitable grate arranged atabout the lower edge of the water-leg, a series of tiles of refractorymaterial supported on said base and held in position between the innerflange and the water-leg, protecting the water-leg from contact with thefire, said tiles being formed each with a vertical channel on its outersurface to permit the passage of the products of combustion downwardlyfrom the combustion-chamber under the lower edge of the boiler to thesurrounding flue.

5. In combination in a steam or hot-water heater, an annular base ofcast metal having an annular, inwardly-extending, flat, upper margin,two concentric flanges formed on said flat margin to maintain inposition the upper portions of the heater supported thereon, apluralityof separate pedestals bolted to said flat margin between saidconcentric flanges to support the boiler, said, pedestals being formedwith lower, securing-flanges, an up per, flat bed for the boiler and anouter flange for fixing the position of the boiler on said bed, thecylindrical boiler having an annular water-leg fitted to said pedestalsand elevated thereby a short distance above the upper margin of thebase, leaving spaces for the passage of the products of combustion, asuitable grate arranged below said water-leg, a series of fire-bricktiles supported on said base and held in position between the inwardconcentric flange and the water-leg forming a continuous lining toprotect the water-leg from contact with the fire and being formed withcorrugations on their inner surfaces and each with-a vertical channelfrom one end to the other on its outer surfaces to permit the pets sageof the products of combustion downwardly from the combustion-chamberunder the lower edge of the boiler to the surrounding fine, water-tubesextending from the water-leg into the combustion-chamber and asheet-metal shell surrounding the boiler and forming a continuous outerflue.

In testimony whereof I have hereunto signed my name.
